US Patent 10907729 Wire-based transmission shifter with integrated electrical switch control

A transmission shifter includes a base defining P, R, N, D gear positions; four electrical dome switches associated with each of the P, R, N, D gear positions, and analog and digital circuits operably connected to the electrical switches, respectively, and associated with the P, R, N, D gear positions. The dome switches are arranged in different patterns in each of the different gear positions, and in combination with pushbutton actuators operate with different actuator motions and with different closure distances and forces to cause reliable ad confirmed intentional actuation, including redundancy. The switches are operably connected to analog and digital circuits, which provides additional functional advantage, reliability, and certainty of intentional operation.
